This was presented as an arithmetic equation, nothing more. Someone tried to find away of validating his opinion that it was expressed ambiguously and brought up programming languages as an example. They didn't apply to anything suggested in the OP, but seemed to stick in some minds as a possibly pertinent argument.
I introduced Japanese into the discussion in the same manner, to suggest an analogy supporting my position on ambiguity, and I shouldn't have. That just further got us off track. Then the idea of cultural imperialism was brought in and that could have really muddied things up.
This is simple arithmetic and the rules of arithmetic are clear on what the expression means. That doesn't suggest that every reader knows the proper way to calculate the answer, but that isn't because there is anything defective about the equation as expressed, which was the only thing the OP was posted for, and what we were discussing.
It looked ambiguous to some. It isn't ambiguous in fact.
